Claims.

This invention `relates tota bagging machine for coal and other lump and granular material.

More particularly the `invention relates to a continuously operating bagller and deliverer.

One important yobjectof the invention is to provide a novel machine of this character whereby measured quantities of material may be delivered to successively positioned bags, the quantities of delivered material being equal throughw out the operation ofthe machine by novel means included therein.

A second important object of the invention is lto provide means whereby the llingoperation may be adjusted to deliver specific quantities of the material.

`A third important object of the invention is to providenovel means for tying the mouths of the bags as they are positioned for delivery from the machine.

With the above and other objects in view the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly set forth g5 in the claims.

In the accompanying drawings, like characters of reference indicate like parts in the several views, .and-

Figure Bis a detail View showing the fastening wire used in connection with this invention.

As best disclosedin Figure 1 the device is provided with a'framefor casing It) through the middie of which extends a vertical shaft Il having a spiineway i2 extending longitudinally thereof. At one side of the frame or casing lli is fixed a bracket i3 carrying a motor I4. This motor is provided with a Ashaft l5 whereon is fixed a sprocket wheel i6. Supported on the frame, at the upper part thereof, is a shaft I'l whereon is a sprocket wheel `lli driven from the sprocket gear le bya chain 19. On-this shaftjisa worm which meshes with a worm wheel 2l xed on a shaft 22 which `carries a sprocket wheel 23 -around whichrpasses the upper end of a bucket Vconveyor 24 delivering material to the machine from la suitable bin or the like. `5

Carriedby the upper end of the frame is an yarcuate hopper 25. On the shaft i5 is a worm 26 which connects with a suitable worm wheel 21 fixed onla shaft 28. On the lower end of this shaft is mounted a pinion 29 which meshes witha 10 gear disk 30 rotatably supported about the shaft ll by bearings 3|. On this gear disk is mounted a circular hopper 32 which is constructed to slide around the lower part of the hopper 25. The disk 30isprovided with la plurality of openings 15 33 in .which are held tubular members .34 conn stituting the measuring means. Obviously, these members 34 are carried around with the disk 3B which latter revolves on the shaft El. On the disk 30 is also provided a series of sockets 35 20 carrying tubular members 33 through which project pairs of pins 3l constituting guide means. Opposite each pair of pins each tubular member 34 isslotted as at 38 to allow avalve33 to slide in and out of the respective member 3ft. Each25 of these valves is carried by an `arm 4i! having a slot 4| therein through which the pin-s 37 pass sothat the arm isguided thereby.

On the shaft rI l is mounted a face cam `l2 the construction of which is shown -best in Figure 6. 30 Thisfaoe cam has a cam groove 43 and each of the members t0 is provided with a downwardly extending end or lug 44 which lits in the groove 43.

Adjacent the lower end of shaft i is fixed, on the shaft, a cam member 45 having a peripheral cam groove `46, Extending downwardly from the members 36 are supports 4.1 having inwardly offset portions 48. Pivoted as at 49 to each of these inwardly offset portions is a lever 50 one end of 40 Awhich engages, as atti, in the cam groove 46. The other end of each lever 53 extends outwardly :and has a pin and slot connection 5l with the stem 52 of a bag platform or supportt. Each of these supports 53 is alined below and concen- 45 trio to a member 34.

Also the shaft H carries a face cam 53 having on its upper face a cam groove 55. Radially disposed to each of these cam grooves is an arm 56 having .a downwardly extending end 5l engaged 50 in said cam groove 55. On the outer end of each arm 56 is carried a socket 53 wherein is revolvably mounted a twister body 59 having gear teeth 6i) longitudinally disposed thereon. Each member -41 is provided with a bearing opening El'wherein 55 is disposed la sleeve 62 in which the member 59 slides. From the outer ends of the members 62 project pairs of arms 63 carrying a bag gripper or support 64. Also a pair of arms 65 constituting twister arms extend outwardly by pivotal connections 66 from lthe member 59 On the cam member 54 is mounted a bracket which carries an arcuate rack 58 which, under cert-ain conditions operates to rotate the member 59 as will be presently described.

At one point in the frame I9 there is provided a conveyor 69 for taking away the bags B which are held on the platform 53.

In the operation of the device, the motor being at work the conveyor 24 carries material up from the ordinary bin and drops it into the hopper 25. Now, as the various members 34 pass beneath the hopper these members 34 are filled. The attendant slips over the lower end of each member 34 a bag B. At this time the Valve 39 is closed by the action of the cam 42. The disk 30 carries this bag-provided member around, it being understood that at the time of passage of the member 34 beneath the hopper 25 the member 34 will be filled with the material to be bagged. As the device is rotated by the motor I4 the valve 39 will be withdrawn toward the center with the consequence that the contents of the member 34 will drop into the bag. At the same time the cam groove 46 will act in conjunction with the opening of the valve 39 to drop the bag as shown at the right-hand of Figure 1. As the bag drops the member 64 will support the upper end portion thereof and, together with the yoke 64", prevent the bag from tilting inwardly out of an upright position. Now as the cam 54 holds the rack 68 stationary the rotation of the members 56 will bring the gear teeth 6D into engagement with the rack 63. This occurs after the bag has been dropped and the attendant has taken a wire, such as shown in 68, and placed it around the neck of the bag with its looped end in engagement with the forward ends of the member 65. When the teeth 60 mesh with the rack 68 this causes rotation of the member 59 and consequently twists the wire ends and draws the wire loop tightly around the neck of the bag. During twisting of the wire about'l the neck of the bag the sleeve 62 is shifted outwardly by the engagement of its arm 54 in the groove 54a and the arm or yoke 64 will serve to push the upper end of the bag together under the member 34 to close and brace the upper end of the bag as the wire is twisted together about the closed upper end or neck of the bag.

Obviously, the cam members 42 and 45 may be adjusted vertically by means of the set screws 10 so that the quantity of material dumped from the members 34 can be regulated.

After the bags have been tied and lowered over the conveyor 69 they are pushed off their supports 53 by yokes 64 carried by arms 64 slidably supported by the supports 41 as a cam 63 keyed to the shaft H reaches its outermost position toward the conveyor 69.

There has thus been provided a simple and eicient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of this invention without departing from the material principles thereof.
